* ARM: Add PSCI supportSascha Hauer2017-02-132-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch contains the barebox implementation for the ARM "Power State Coordination Interface" (PSCI). The interface is aimed at the generalization of code in the following power management scenarios: * Core idle management. * Dynamic addition and removal of cores, and secondary core boot. * big.LITTLE migration. * System shutdown and reset. In practice, all that's currently implemented is a way to enable the secondary core one some SoCs. With PSCI the Kernel is either started in nonsecure or in Hypervisor mode and PSCI is used to apply power to the secondary cores. The start mode is passed in the global.bootm.secure_state variable. This enum can contain "secure" (Kernel is started in secure mode, means no PSCI), "nonsecure" (Kernel is started in nonsecure mode, PSCI available) or "hyp" (Kernel is started in hyp mode, meaning it can support virtualization). We currently only support putting the secure monitor code into SDRAM, which means we always steal some amount of memory from the Kernel. To keep things simple for now we simply keep the whole barebox binary in memory The PSCI support has been tested on i.MX7 only so far. The only supported operations are CPU_ON and CPU_OFF. The PSCI and secure monitor code is based on the corresponding U-Boot code. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: Fix appended device tree when CONFIG_OFTREE is enabledSascha Hauer2016-11-081-2/+10
| | | | | | | | | When CONFIG_OFTREE is enabled the appended device tree is unflattened and put into data->of_root_node, but there it is never used again. To actually use the appended device tree put it into data->oftree instead. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: bootm: Fix free_mem calculation when initrd is givenSascha Hauer2016-10-181-1/+1
| | | | | | | | | | | | | | When a initrd is given we calculate the next free memory position as: free_mem = PAGE_ALIGN(initrd_end); This is wrong when initrd_end exactly falls on a page boundary. In this case PAGE_ALIGN() does nothing and free_mem becomes initrd_end and the following bootm_load_devicetree() and thus booting fails with -ENOMEM. Fix this by correctly advancing to the next free memory position. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: bootm: recalculate decompression spaceStefan Müller-Klieser2016-07-041-3/+15
| | | | | | | | | | | | | | | | According to the kernel documentation it is recommended to place the compressed image between 32 MiB and 128 MiB. The DTB and initrd should be placed above 128 MiB. We will follow the recommendation as long as we have enough RAM. If this is not the case, we fall back to the scheme. This change is required because of the ARM default kernel config changes regarding RODATA layout, which lead to an increased compression factor of the kernel image. This should be regarded as an intermediate solution until there is a mechanism for the kernel image to report the decompressed layout requirements to the bootloader.

* bootm: Move bootm options to common/KconfigSascha Hauer2016-05-101-2/+2
| | | | | | | | | | | | bootm has a C API, so the bootm options have to depend on the option providing the bootm code (CONFIG_BOOTM), not on the option providing the command (CONFIG_CMD_BOOTM). Fixing the dependencies makes it possible to fully use bootm from C without enabling the bootm command support. This also removes the CMD_ prefix from the options which means we have to update the defconfigs aswell. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: Rework vector table setupSascha Hauer2016-04-011-0/+1
| | | | | | | | | | | | | | | | | | | The current vector table setup has some shortcomings. First of all currently the case when the high vectors are inside SDRAM (that is, SDRAM reaches the end of the address space) is not supported. In this case we create a secondary page table for the section containing the vectors which gets overwritten by the general SDRAM secondary page table entries creation afterwards. On ARMv7 and later the exception table setup can be improved: Here the vector table address is configurable in the VBAR register. We can use this register to skip remapping the vector table. With this patch we first try to use the VBAR register before doing something else. Also, when we have to use the high vectors we first try a request_sdram_region to test if the vector table memory is already mapped. While at it sprinkle some comments into the code.

* arm: bootm: be more clever about kernel spacingLucas Stach2016-03-011-0/+8
| | | | | | | | | | When the kernel load address is chosen by the user/image we need to check if the kernel needs to relocate itself before decompression.

* bootm: add initial FIT supportJan Luebbe2016-01-261-0/+8
| | | | | | | | | | | | | | | This implementation is inspired by U-Boot's FIT support. Instead of using libfdt (which does not exist in barebox), configuration signatures are verified by using a simplified DT parser based on barebox's own code. Currently, only signed configurations with hashed images are supported, as the other variants are less useful for verified boot. Compatible FIT images can be created using U-Boot's mkimage tool.

* ARM: Remove kernel booting call for thumb2 modeTrent Piepho2015-12-041-12/+0
| | | | | | | | | | | | | | | | | | | | | | | The asm code to do the actual call into the kernel (or another barebox) when compiled in thumb2 mode isn't necessary. gcc generates a perfectly good calling sequence from a normal function pointer call. If it didn't, the code in bootstrap_boot() that uses a function pointer to jump to the 2nd stage barebox from an xloader wouldn't work. It appears to be allowed that the call to kernel() could return, as neither start_linux() nor kernel() are marked noreturn, and there is code after calls to start_linux(). The asm code has a bug in this case, as it uses bx and not blx, and thus doesn't set the link register. Since it's a tail call, this would be okay, but only if the LR value from the start of start_linux() (and the callee-saved registers) are restored beforehand, which isn't done. The gcc generated call sequence will do this. Signed-off-by: Trent Piepho <tpiepho@kymetacorp.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-271-3/+4
| | | | | | | | | | | | | | | | | | | | | | This replaces the reset_cpu() function which every SoC or board must provide with registered handlers. This makes it possible to have multiple reset functions for boards which have multiple ways to reset the machine. Also boards which have no way at all to reset the machine no longer have to provide a dummy reset_cpu() function. The problem this solves is that some machines have external PMICs or similar to reset the system which have to be preferred over the internal SoC reset, because the PMIC can reset not only the SoC but also the external devices. To pick the right way to reset a machine each handler has a priority. The default priority is 100 and all currently existing restart handlers are registered with this priority. of_get_restart_priority() allows to retrieve the priority from the device tree which makes it possible for boards to give certain restart handlers a higher priority in order to use this one instead of the default one.

| * Add support for metadata in barebox imagesSascha Hauer2014-08-072-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's often useful to get some information about a barebox image before starting or flashing it. This patch introduces barebox Image MetaData (IMD). When enabled a barebox image will contain a list of tags containing the desired information. We have tags for: - the barebox release (2014.07.0-00160-g035de50-dirty) - the build timestamp (#741 Mon Jul 28 15:08:54 CEST 2014) - the board model the image is intended for - the device tree toplevel compatible property Also there is an additional generic key-value store which stores parameters for which no dedicated tag exists. In this patch it is used for the memory size an image supports. Since there is no fixed offset in a barebox image which can be used for storing the information, the metadata is stored somewhere in the image and found by iterating over the image. This works for most image types, but obviously not for SoC images which are encoded or encrypted in some way. There is a 'imd' tool compiled from the same sources for barebox, for the compile host and for the target, so the metadata information is available whereever needed. For device tree boards the model and of_compatible tags are automatically generated. Example output of the imd tool for a Phytec phyFLEX image: build: #889 Wed Jul 30 16:08:54 CEST 2014 release: 2014.07.0-00167-g6b2070d-dirty parameter: memsize=1024 of_compatible: phytec,imx6x-pbab01 phytec,imx6dl-pfla02 fsl,imx6dl model: Phytec phyFLEX-i.MX6 Duallite Carrier-Board Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | The Android image format makes the same mistake as the U-Boot uImage format: It makes the load address mandatory.
